Question
To move a large crate of mass 32.0 kg across a rough floor, with coefficient
of kinetic friction between the crate and the floor is k = 0.45, you pull on it
with a Force P at an angle of 30o above the horizontal and some else also
pushes on the crate with a force F at an angle 45o below the horizontal. (The
applied forces, F & P, on the crate starts it moving.) (a) Find the Normal
force acting on the crate. (b) Find the acceleration of the crate if the applied
force is F = 130 N & P = 300 N.
